U.S. most armed country with 90 guns per 100 people

The United States has 90 guns for every 100 citizens, making it the most heavily armed society in the world, a report released on Tuesday said.

U.S. citizens own 270 million of the world's 875 million known firearms, according to the Small Arms Survey 2007 by the Geneva-based Graduate Institute of International Studies.

About 4.5 million of the 8 million new guns manufactured worldwide each year are purchased in the United States, it said.

"There is roughly one firearm for every seven people worldwide. Without the United States, though, this drops to about one firearm per 10 people," it said.

India had the world's second-largest civilian gun arsenal, with an estimated 46 million firearms outside law enforcement and the military, though this represented just four guns per 100 people there. China, ranked third with 40 million privately held guns, had 3 firearms per 100 people.

Germany, France, Pakistan, Mexico, Brazil and Russia were next in the ranking of country's overall civilian gun arsenals.

On a per-capita basis, Yemen had the second most heavily armed citizenry behind the United States, with 61 guns per 100 people, followed by Finland with 56, Switzerland with 46, Iraq with 39 and Serbia with 38.

France, Canada, Sweden, Austria and Germany were next, each with about 30 guns per 100 people, while rer many poorer countries often associated with violence ranked much lower. Nigeria, for instance, had just one gun per 100 people.
